ASP.NET MVC在URL中隐藏内容目录 [英] ASP.NET MVC Hide Content Directory in url

问题描述

有人要求我查看是否有可能阻止Content目录在Asp.Net MVC 3.0应用程序中显示为url的一部分.例如目前，当我要在Content文件夹的子目录中查看图像时，URL如下:

I've been asked to see if it's possible to prevent the Content directory from appearing as part of the url in an Asp.Net MVC 3.0 application. For example at present when I want to view an image in the sub directory of the Content folder the url is as follows:

http://localhost:[port]/Content/sub/test.bmp

我们希望将其简单显示如下:

While we are looking to display it simply as follows:

http://localhost:[port]/sub/test.bmp

Test.bmp实际上仍将存在于我们仅希望隐藏内容"部分的服务器上的内容"文件夹的子目录中.

Test.bmp will still physically exist in the sub directory of the Content folder on the server we just want to hide the Content part.

有什么建议吗?我可以看到掩盖控制器的方法，但看不到目录.

Any suggestions? I can see ways of masking controllers but not directories.

推荐答案

解决方案如下(目前这只是准系统代码，需要整理):

Solution is as follows (this is just the barebones code at the moment and needs to be tidied up):

已将此路由添加到Global.asax:

Added this route to Global.asax :

routes.MapRoute("Content",
                "{dir}/{file}",
                new { controller = "Content", action = "LoadContent"});

添加了此控制器来处理请求:

Added this controller to handle the request:

namespace demos
{
   public class ContentController : Controller
    {
        public ActionResult LoadContent(string dir, string file)
        {
            string fileName = Server.MapPath(Url.Content("~/Content/" + dir)) 
            fileName += "\\" + file;            

            // stream file if exists    
            FileInfo info = new FileInfo(fileName);
            if (info.Exists)
                return File(info.OpenRead(), MimeType(fileName));


            // else return null - file not found
            return null;            
        }


        private string MimeType(string filename)
        {
            string mime = "application/octetstream";
            var extension = Path.GetExtension(filename);
            if (extension != null)
            {
               RegistryKey rk = Registry.ClassesRoot.OpenSubKey(extension.ToLower());

                if (rk != null && rk.GetValue("Content Type") != null)
                    mime = rk.GetValue("Content Type").ToString();
            }

            return mime;
        }
    }
}
